' in Means for Vehicle Tires, of which the fo lowing isa specification.

My invention relates to skid preventing means for rubber tired wheels of motor propelled vehicles.

l am aware that' skid preventing means have been heretofore employed wherein a chain construction is detachably placed about the tires. However, certain objecl tionable features have been present in such dll devices, for instance, the breaking ot the members in contact with the roadway and tread of the tires and their subsequent dying 1: about and striking portions of the vehicles;

further, the clasps whereby the device is attached have been extremely dimcult ot manipulation; further, the crossmembers ol such chain devices have been subject to relative displacement easily becoming entangled with one another, and do not remain in the osition about ther tire in which they have een placed; and further, no means have n employed for maintaining equal tension on all members of the device and capable of taking up wear-in the chain.

The primary object of the present invention is to. provide a detachable nonskid ding attachment for vehicle wheels in which the members for preventinrlr said skidding are maintained at all time/s 1n close engagement with the tire tread and the side portions thereof.

An additional object of my invention is to provide means, whereby' when the tire is compressed the nonskiddjng members s annin the same may yield to move with t efportion ot the tire so compressed without varying the tension maintained on remainin members of said device. v

tl invention consists in the revision of a skid preventing device of whic all ortions thereof are entirely tree of the. elly further, in means tact with the 'roadway lis compressed, the anti-skid 'mbers located at such com I prd portions may ybe permitted to Ayield without adecti r the tension on the skid preventing on the `remaining por- 'ing mein maintainin means tor holding the several uniform tensionk members o the device in about the wheel. Y Y

My invention further consists in the parts, combination, arrangement and construction ohpartsand in the details otconstruction as erein set forth and claimed.

Each ol the hook rings ll is provided with ahook lt adapted to cage one end of a triangular connector 17 wich in turn is connec to separable limiting Inbers 18 and 19 disposed to either side ot the tire comlprising preferably twist linksreceived in the apexes ot thetrianar connectors, and each having hook portions 20 engagingl circular 4connecting members 2l and 22 respectively.,

, ln order to edectively hold the various rs l2 and 13 disposed to either titl the

lil@

members about the wheel with a uniform tensioma separablev cable 23. is connected by me'ans of hook rings 24 secured to circular connecting members 21 and 22 respectively.

'the device to be readily lattached to the wheel. This clasp comprises a link 36 having eyes37 and 38, one of which is engaged by one end of the separable members the other eye engaging 'a c osed eye 39 of a closure lever 40:.' This closure lever comprises an o en eye'41 loca adjacent the eye 39 whic is engadby the other end of the separable inemrs. The eye 41 is extended to form a closure cam 42 which in turn has a locking shank 43-` thereon. The lockingI shank 43 is adapted to he held in place against the link 36 by a collapsible coil spring 44 received about the link and the shank.

When it is desired to remove the device vfrom the wheel, the spring is collapsed'whiclil permits the closure lever to o n outwardly and thereby permit one end o the separable' members to be released afterwhich the device is easily detached.

ln placing the device on the wheel, the clasps 35 of all the separable members are opened, the cable 23 being disengaged from thefhooks of the hook rings 24. The device is then placed about the wheel, the clasps being readily closed b passingthe free ends of the separable mem rs over the closure levers 40. These levers are then closed which causes the separable members to be drawn together. The locking shank is than held in contact with the links 36 when the springs v44 are collapsed. Upon the springs being released, the saine inclose -both t e links 36 and the locking Shanks 43, which eectivel hold them against unintentional release.` he cable 23 is next inserted inthe hooks 25 and its clasprlocked in similar inanner. The proper tension may new be im-I parted to the members of the deviceby acll justing the turn buckle 26. i

)It will be observed that as tension is im@ parted bythe cable to the limitin member titi betweenV the `points at which t e hooks 22 are secured, hatten out of the tread in contact with the roadway will not disturb the location and tension on such members as are not in contact therewith. A slack condition in any of the cross members is l: taken care of immediately at such at which, thevslack occurs, without affecting in any manner or releasing the tension .on other of the cross members.

My improved deviceis of extremely simplied construction, readily attached and eficient in its operation by reason of the readily operable clasps, attention afterwards being imparted to the entire device by the turnbuckle. Also no parts of my improved device are engaged with the folly or the spokes of the \wheel, which featurev avoids injury or scratching thereof.

The parts of the device which engage the roadway are all maintained relatively taut .and held against movement relative to eachY` other so that the throw of the parte during rapid'motion of the wheel, an consequent digging or injury to the road are almost eny obviated. Bynmaintaining such equal tire tension on all of the members comprising my device rapid creeping of the chain about the tread of the wheel is almost entirely avoided, however, a slight creeping edect is of an advantage as the tire is not subject to such vigorous wear as when the chains are retalned in one particular position on the tire.

What l claim as new anddesireto secure by Letters Patent is:

1.1m skid preventing means for lvehicle.
